4ec3ed7f5e PCI: imx6: Fix imprecise abort handler 
An imprecise abort is triggered when a port behind a switch is accessed
and no device is present.  At enumeration, imprecise aborts are not enabled
thus this ends up getting deferred until the kernel has completed init.  At
that point we must not adjust PC - the handler must do nothing, but a
handler must exist.

This fixes random crashes that occur right after freeing init.

9b5cd0948b PCI: imx6: Remove redundant dev_err() in imx6_pcie_probe() 
There is an error message within devm_ioremap_resource()
already, so remove the dev_err() call to avoid redundant
error message.
